This politically stable Central American country has protected over 25% of its land mass as National Parks, and its economy depends heavily on tourism. Having both a Pacific and Caribbean coast, separated by central mountains, creates diverse habitats for migrants from North and South America, and the establishment of endemic species. Our 2017 trip focused more on the birds along the Pacific coast; however, in 2012 we also spent time along the Caribbean coast, in the central valley, and on the slopes of the David Hoar: Retired University Professor in the field volcanoes.

Bird Week is our way of helping everyone become more aware of birds around the city. Our theme this year will be garden birds. Take a look at the events and join in the fun.” - Rob Butler, Chair of Bird Week Blackbirds, crows, and chickadees – Get to know your birds during Bird Week From bird nerd to bird curious, from wise old owl to adventurous tot, there is an event for everyone during Bird Week: May 6-13, 2017. Bird Week is a week-long series of events to celebrate Vancouver’s birds. It was inspired by World Migratory Bird Day, a United Nations-sponsored initiative that recognizes the importance of birds as key indicators of our environment’s health. During Bird Week, there will be bird-related workshops, walks, talks, exhibitions, and lectures across Vancouver. All events are free. Plan to join us in 2018 when Bird Week coincides with the International Ornithological Congress in Vancouver from 19 to 26 August.

Their larvae (white grubs) are below-ground pests of turfgrass, corn, and other agricultural crops. In some regions, such as the Midwestern United States, they are among the most important pest of turfgrass, building up in high densities and consuming roots below the soil/thatch interface. Five species are known to be important pests of turfgrass in North America, including northern masked chafer, Cyclocephala borealis Arrow; southern masked chafer, Cyclocephala lurida Bland [for- http://jipm.oxfordjournals.org/ merly Cyclocephala immaculata (Olivier)]; Cyclocephala pasadenae (Casey); Cyclocephala hirta LeConte; and Cyclocephala parallela Casey.

The two species have overlapping (Table 1).

  • White Grubs (Japanese Beetle, May/June Beetle, Masked Chafer, Green June Beetle, European Chafer, Asiatic Garden Beetle, Oriental Beetle, Black Turfgrass Ataenius)
    White Grubs (Japanese Beetle, May/June Beetle, Masked Chafer, Green June Beetle, European Chafer, Asiatic Garden Beetle, Oriental Beetle, Black Turfgrass Ataenius) There are 8 different white grubs that are commonly known to cause turfgrass plant damage. They include the Japanese beetle, May and June beetle, masked chafer, green June beetle, European chafer, Asiatic garden beetle, oriental beetle, and black turfgrass ataenius. They all do the most damage in their larval stage, although some adults can also cause damage. Japanese Beetle (Popillia japonica) Japanese beetles are concentrated mostly in the northeastern and Mid Atlantic states. The Japanese beetle larvae are the primary cause of turf damage. They feed on turfgrass roots, which causes yellowing and a wilting, thinning appearance to the plants. Turf that has been damaged can easily be rolled or lifted back from the soil because the grubs have eaten through the fibrous roots. Typical Japanese beetle raster pattern. Typical Japanese beetle adult.
